Is the mitochondria studded with ribosomes?

Yes, mitochondria have their own ribosomes. These ribosomes are responsible for producing some of the proteins needed by the mitochondria to generate energy through a process called oxidative phosphorylation.


Why do mitochondria have their own ribosomes?

Mitochondria have their own ribosomes because they are believed to have originated from ancient bacteria that were engulfed by a eukaryotic cell. These ribosomes help mitochondria synthesize some of their own proteins independently from the cell's main protein synthesis machinery. This allows mitochondria to quickly respond to their metabolic needs.


Do mitochondria and chloroplasts contain ribosomes?

Yes.They have 70s ribosomes. They are similar to bacteria


Mitochondria contain their own so they can produce their own proteins?

Mitochondria contain their own DNA and ribosomes so they can produce some of their own proteins, particularly those essential for their function in generating energy through cellular respiration. This allows mitochondria to regulate their own processes independently of the cell's nuclear DNA.


How is mitochondria and chloroplasts the same?

They have own DNA.Both have 70s ribosomes


Can the mitochondria manufacture some of their own proteins?

yes they can. They have their own ribosomes which synthesize proteins


Eukaryotic mitochondria have their own 70S ribosomes and circular DNA?

Yes, this is correct. Eukaryotic mitochondria have their own set of ribosomes called mitoribosomes, which are 70S in size. Mitochondria also have circular DNA that contains genes necessary for mitochondrial function and replication.


When compared to other cells cells with more mitochondria will be able to?

Mitochondria can replicate themselves. They also have own ribosomes.


What types are the mitochondria and ribosomes?

Mitochondria have 70s ribosomes.Eukariyotes have 80s ribosomes.


What is the other cellular component which has it own DNA and ribosomes?

Mitochondria is the only animal cellular organelle which has its own DNA & ribosomes becoz it produces ATP molecules.


Which is bigger a ribosome or a mitochondria?

Mitochondria are bigger than ribosomes. Ribosomes can be found in mitochondria


What organelle contains its own DNA and ribosomes?

Mitochondria are the organelles that contain their own DNA and ribosomes. They are often called the powerhouse of the cell because they generate energy for the cell through the process of cellular respiration. Mitochondria have a double membrane structure and their own genetic material separate from the cell's nuclear DNA.
